To [all whom, it may concern.-

Be it known that I, ENos CAREY, a citizen of the United States, residing in Grant county and in the State of Indiana, have invented new and useful Improvements in Harvesting-Machines, of which the followin is a full and comprehensive exposition an specification, such as will enable others familiar with the art to which this invention appertains to make and use the same with absolute exactitude.

My present invention relates to improvements in harvesting machines or the like, and more particularly to the draft-frame and operating gears, and means for positively and fully throwing the machine into and out of gear, and means for equalizing the strain on the gear mechanism and frame.

Broadly speaking my object is to provide improvements in harvesting machinery which will be simple and practical in construction,

positive in action, strong and durable in construction, and which can be manufactured and sold at a comparatively low price, and at the same time providing such a construction which may be employed in connection with various kinds of machines, and machines for various purposes, the several details being suitably modified to meet the various desired applications to which the invention is applicable.

Other minor objects and particular advantages will present themselves in the course of the ensuing specification.

One manner for the carrying out of the objects stated, and that which I have determined to be the most ractical, is exemplified in the accompanying drawings, in which- Figure 1 is a plan view of my entire invention; Fig. 2 is a side elevation thereof, the near traction-wheel being removed, and as taken on the line YY of Fig.- 1 and taken in the direction indicated by the arrows on said line; Fig. 3 is a horizontal central sectional view of the machine, as taken on the line XX of Fig. 4, and as taken in the direction indicated by the arrows on said line; Fig. 4 is a front elevation of my machine; Fig. 5 is a plan view of the under side of the machine; Fig. 6 is an inside face viewof one of the traction wheels and Fig. 7 is rearface View of one of the clutches.

Similar reference characters denote like parts throughout the several views of the drawings.

In order that my invention may be understood and its several advantages fully appreciated I will now take up a detail description thereof and will refer to and describe the construction and operation of the several parts as comprehensively and as briefly as I may.

By reference to the accompanying drawings it will be noted that a majority of the parts shown on one side of the machine are duplicates of like parts on the opposite side thereof, therefore, for convenience of description, I will refer to the parts on the right-hand side of the machine by numerals, and the like or concert parts on the left by similar numerals with exponents, and where the parts are single they will be denoted simply by letters.

In the drawings the numerals 1 and 1 designate the traction or ground wheels of my machine, which wheels are revolubly mounted on spindles therefor on the main-axle A in any well known manner, the body of said axle A, between the wheels, being formed substantially square. Formed integral with the inner faces of the wheels 1 and 1 are the respective bevel gear pinions 2 and 2, which consequently revolve at all times with their respective wheels.

Mounted on the main-axle A, and located parallel with each other, are the main sills 3 and 3, being notched or gained over the axle A and secured by bolts thereto, sulistantially as indicated in Fig. 1. The ends of said sills are connected by the respective front and rear ties B and C; said. ties being connected to the ends of the sills by bolts as shown. Secured to the axle A, immediately to the right-hand side of the center thereof, is the tongue D which extends forward through an aperture therefor formed through the tie B, and it provides means for attaching to the machine for its propulsion.

Channels are formed in the underfaces of the sills 3 and 3, longitudinally thereof, in which may revolve the shafts 4 and 4, respectively, said shafts of course extending through apertures therefor formed through the axle A, as shown in Fig. 3. The ends of shafts abut the cross-ties B and O which pre vent the shafts from moving endwise; the axle holding revolubly the central portion of said shafts; and the end portion of said shafts are held in the channels therefor by the caps 5-- 6 and 56, respectively, as shown in Fig. 5. Secured on the rear portions of the shafts 4 and 4 are miter-gear wheels 7 and 7, respectively, spaces being formed in the sills for that purpose as indicated in Fig. 2.

Mounted revolubly between and carried by the rear portions of the sills 3 and 3 is the intermediate shaft E, on the end portions of which are secured the miter-gear wheels 8 and 8, which latter mesh continuously with the miter-gear wheels 7 and 7, respectively. Also secured on the shaft E, slightly to the right of the center thereof, is the bevel-gear F, meshing with the miter-pinion Gr. The said miter-pinion G is secured on the rear end of the operative shaft H. The said shaft H extends through apertures therefor formed through the axle A and the tie B, and its outer end may be attached to other parts not shown as for inst ance thecutting mech anism. The letter I denotes a contact-plate secured to the rear face of the axle A for the Initerpinion head to contact with, as shown.

Revolubly mounted on the forward portions of the shafts 4 and 4 are the slidable bevel-gear pinions 9 and 9, respectively, which are adapted to mesh with the bevelgears 2 and 2, respectively, of the tractionwheels as indicated, and which are adapted to slide forward on their respective shafts to disengage them from said bevel-gears 2 and 2 when desired. The means for moving said pinions endwise is controlled by a single lever, and it is shown most clearly in Figs. 1 and 5, and may be described as follows: E. tending across between the sills 3 and 3, immediately in front of the axle A, is a rod J having downwardly projecting arms J and J integral therewith and lying near the sills and having right-angular inturned pivots as shown. The rod J is pivoted to the sills 3 and 3 by the hangers 10 and 10, respectively.

From the central portion of the rod J an operating lever K extends upward, as shown, whereby said rod may be rotated. .A flange projects forward from the gear-pinions 9 and 9, in the peripheries of which are formed channels for the respective loops 12 and 12. After encircling their respective channels, as shown, said loops extend inward and then rearward forming the arms 11 and 1 1 and having their rear ends pivoted to the said pivots of the respective arms J and J, of the rod J. By the above described arrangement it is apparent that as the lever K is moved forward and backward the pinions 9 and 9 will be moved synchronously into and out of gear with the respective gears 2 and 2.

The clutches which I will now describe consists each of disks 13 and 13, which are revolubly mounted on the respective shafts 4 and 4. The forward faces of said disks are provided with a series of square-cut lugs and corresponding equal indentations to engage the g respective indentations and lugs formed oppositely thereto on the faces of the gear-pinions 9 and 9; and around the peripheries of said disks are formed channels for the hangers 14 and 14, respectively, which extend around thereunder with their ends ex tending up through the sills 3 and 3, respectively, on the upper faces of which-they are secured by nuts, as indicated in Fig. which arrangement said disks are prevented from longitudinal movement along the shafts but are revoluble thereon. Permanently secured on the shafts 4 and 4 and contacting with the rear faces of the respective disks 13 and 13 are the ratchet Wheels 15 and 15. Mounted on the rear faces of the disks 13 and 13 are the respective pawls 1616 and 16-16", as indicated most clearly in Fig. 7. Said pawls are resiliently heid in contact with the respective ratchet wheels by springs therefor as indicated. A cavity is formed in the sills 3 and 3 for the respective ratchet mechanism and for the respective gear pinions to operate in, the latter having sufficient space for their forward and h ackward movements. 7

Operation: From the above it will have been determined that the operation of my invention is comparatively simple and unique, in that the construction may be propelled by attachment to the tongue and carried over the ground on the traction wheels. When being moved merely for the purposes of transportation the lever K is turned back which will disconnect the gears 9 and 9 from their respective gears 2 and 2, and thereby allowing the traction wheels to turn idly on the axle,at which time every part of the mechanism will be inoperative and will remain relatively stationary the same as if it were being transported by a wagon. the lever K be turned forward then the gears 9 and 9 will engage with the gears 2 and 2, at the same time the gears 9 and 9 will en gage the disks 13 and 13 and, if the machine be propelled forward, the pawls will engage the ratchet wheels aforesaid and they in turn will revolve the shafts 4 and 4, and the latter by means of the gear wheels 7 and 7, and 8 and 8, will revolve the shaft E, and it in turn the shaft H by the means stated. Should the machine for any reason be pro- Should r pelled rearward then the pawls aforesaid will act reversely on the ratchet-wheels without operatingthe machinery. It should also be noted that should one of the tractionwheels move more slowly than the other, as in turning, then the ratchet mechanism of that wheel will compensate therefor by acting reversely. By this construction it is apparent that both traction wheels contribute, not only to carrying the machine, but acting equally on the machinery and thereby equalizing the strain and reducing the wear and danger of breakage to a minimum. It should also be noted that in this construction I practically provide a twin operating mechanism, whereby if one should become inoperative, inadvertently, then the other may temporarily carry the lo ad. And finally a very important feature is the construction of the frame and the manner of positioning and mounting the various parts thereon, which it is evident forms a very rigid and secure construction, while at the same time allowing for all proper flexibility.

From the above description, taken in connection with the accompanying drawings, it will be seen that I have produced an improved construction for harvesting machines or the like which embody the objects hereinbefore stated, and while I have shown and described the bestmeans now known to me for carrying out my invention in a practical manner I desire that it be understood that I do not restrict myself to the exact details of construction shown and described, but hold that any changes or variations therein as would suggest themselves to the ordinary mechanic would clearly fall within the limits and scope of my invention.
